Creating Carbon Removal Credits is a
3-step process
ONCRA is open source and based on established and scientifically proven methods. We follow a strict 3-step process of quantification, certification and verification.
Quantify
Use our open calculation estimation model to gather your real life data and work out your business case. Do not hesitate to contact us if you need help.
The more accurately you quantify your removal, the greater the chance that your project will be positively assessed.
Certify
Enter your project data to receive a draft verification report. You may use all established accounting methods available in our repository.
After agreeing to a positive verification, our team will contact you to set up an ONCRA Carbon Accounting Agreement (OCAA).
Verify
All provided data will be empirically verified, and an MRV Protocol will be followed to keep track of your actual removal. You must track sales of credits on our ledger, but can sell them anywhere. And only after you sell credits, buyers pay verification costs through a fee of 7% included in the sales price.
“By performing a ‘doughnut check’ we evaluate if the project operates within the planetary boundaries. Multiple benefits like biodiversity, clean water and meaningful jobs, are examples of how ONCRA removal credits tick many SDGs and result in a holistic approach.”
